Question

State five applications in real life showing Joule-Thomson effect.

Answer 1

The Joule-Thomson effect is the change in gas temperature as it flows from a region of high pressure to a region of low pressure. Applications:

1. Gas liquefaction (temperature drops below boiling point)
2. Gas separation (temperature drops below boiling poing of one of the gases making up the mixture and we can separate the liquid from the remaining gases)
3. Refrigeration (closed loop of pressurisation and expansion of refrigerants)
4. Air conditioning (same principle)
5. Determining equation of state of the gas from JT coefficient
